Peptide Glossary — Key Terms & Definitions
A reference glossary of peptide research terminology, scientific acronyms, and clinical concepts used across The Peptide Dispatch.
- Lyophilized
- Freeze-dried. Removes water from peptide to improve stability for storage and shipping.
- Reconstitution
- The process of dissolving lyophilized peptide powder into bacteriostatic water.
- BAC Water
- Bacteriostatic water — sterile water with 0.9% benzyl alcohol. Used as diluent for peptides.
- SubQ
- Subcutaneous — injection into the fatty tissue layer beneath the skin.
- IM
- Intramuscular — injection directly into muscle tissue.
- Half-Life
- Time for the peptide concentration in the body to reduce by 50%.
- GHRH
- Growth Hormone Releasing Hormone — stimulates pituitary release of growth hormone.
- GHRP
- Growth Hormone Releasing Peptide — mimics ghrelin to stimulate GH release.
- GLP-1
- Glucagon-Like Peptide-1 — incretin hormone that regulates blood sugar and appetite.
- RUO
- Research Use Only — regulatory classification indicating a substance is not approved for human use.
- Peptide Bond
- The chemical bond linking amino acids in a peptide chain (–CO–NH–).
- Amino Acid
- The building blocks of peptides and proteins. 20 standard amino acids exist in biology.
